An ECU of the second vehicle processes data received from the first communication device and data indicative of a predicted path of travel of the second vehicle to determine a potential collision between the first vehicle and the second vehicle during a turning maneuver of the first vehicle toward the second vehicle. Responsive to determination of potential collision between the first vehicle and the second vehicle, the ECU controls braking and/or steering of the second vehicle.

CROSS REFERENCE TO RELATED APPLICATIONS

The present application is a continuation of U.S. patent application Ser. No. 15/832,801, filed Dec. 6, 2017, now U.S. Pat. No. 10,347,129, which claims the filing benefits of U.S. provisional application Ser. No. 62/431,083, filed Dec. 7, 2016, which is hereby incorporated herein by reference in its entirety.

FIELD OF THE INVENTION

The present invention relates generally to a sensing or communication system for a vehicle and, more particularly, to a vehicle sensing or communication system that utilizes one or more sensors at a vehicle and that utilizes a communication device to communicate with other vehicles.

BACKGROUND OF THE INVENTION

Use of imaging sensors in vehicle imaging systems is common and known. Examples of such known systems are described in U.S. Pat. Nos. 5,949,331; 5,670,935 and/or 5,550,677, which are hereby incorporated herein by reference in their entireties.

Recently developed Dedicated Short Range Communication (DSRC) radio technology (as known in the art) enables communications-based active safety systems. Communication links for such applications need to be reliable, high speed, low latency links that are immune to extreme weather conditions and that work reliably in high speed mobility conditions and multipath roadway environments.

In 2012, there were 3,921 people killed and 104,000 people injured in crashes involving large trucks. In the United States, 333,000 large trucks were involved in traffic crashes during 2012. According to many insurance carriers, in over 90 percent of right turn squeeze situations, either the truck driver is cited for unsafe turning or even without a citation issued, the trucking company still must pay for the damage to the other vehicle. Because of the length of the truck, if the truck driver or the other vehicle driver misjudge the path of travel of the inside tire, the vehicles end up in a crash. Right turns are typically a problem for trucks. Accidents can occur when other vehicles squeeze into the area along the right side of the truck. The other vehicle may be attempting to pass on the right or make a right turn inside of the turn of the truck.

SUMMARY OF THE INVENTION

The present invention provides a driver assistance system for a vehicle that utilizes one or more sensors (such as a camera of the vehicle) and uses a dedicated short range communication (DSRC) radio of the vehicle to communicate to a DSRC radio of another vehicle. The communication system for vehicles comprises a first communication device disposed at a first vehicle and wirelessly transmitting data indicative of a path of travel of the first vehicle, and a second communication device disposed at a second vehicle and receiving the transmitted data from the first communication device of the first vehicle. A control is operable to process data received from the first communication device and data indicative of a projected path of travel of the second vehicle to determine a potential collision between the first and second vehicles. Responsive to determination of a likelihood of collision between the first and second vehicles, the control generates an alert to a driver of the second vehicle.

Optionally, the first vehicle may be a truck and the second vehicle may be a vehicle or car at or near the truck when the truck is about to commence a turning maneuver. Optionally, the second vehicle may be a truck and the first vehicle may be a vehicle or car at or near the truck when the truck is about to commence a turning maneuver.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

A vehicle driver assist system and/or object detection system and/or alert system operates to capture images exterior of the vehicle and may process the captured image data to display images and to detect objects at or near the vehicle and in the predicted path of the vehicle, such as to assist a driver of the vehicle in maneuvering the vehicle in a rearward direction. The vision system includes an image processor or image processing system that is operable to receive image data from one or more cameras and provide an output to a display device for displaying images representative of the captured image data. Optionally, the vision system may provide display, such as a rearview display or a top down or bird's eye or surround view display or the like.

The present invention provides an alert or vehicle control system that functions to reduce or avoid collisions between a truck and a vehicle or car, such as when a truck is making a right hand turn with the other vehicle at the right side of the truck or in the street onto which the truck is turning. Because of the length of the truck, during a turn the inside tire of the truck takes the path as shown in FIGS. 1 and 2, and if the truck driver or other vehicle driver misjudge the path of travel of the inside tire, the vehicles may collide. In the U.S., right turns are a frequent problem for trucks, and accidents can occur when other vehicles squeeze into the area along the right side of the truck. The other vehicle may be attempting to pass on the right or make a right turn inside of the turn of the truck.

The present invention is applicable to trucks, such as are used for transporting freight. A truck, as the term is used herein, comprises tractor-trailer trucks or semi-trucks (having a cab and a multi-axle trailer) classified in Class 7, 8 or 9 (U.S. Commercial Truck GVWR classifications). Thus, as an example, a truck (as the term is used herein) may comprise a Class 8 tractor-trailer or “18-wheeler” truck having a gross vehicle weight rating above 33,000 lbs.

Referring now to the drawings and the illustrative embodiments depicted therein, a truck 100 (FIG. 3), such as a semi-truck with a long trailer, is equipped with a communication system 101 with a turn alert and a brake system control module. The communication system 101 includes a DSRC radio 106 and a DSRC antenna 105, with the DSRC radio 106 communicating with an Electronic Control Unit (ECU) 107. The ECU 107 is in communication (such as wired or wireless communication) with a vehicle bus of the truck 100, and communicates with a Human Machine Interface (HMI) 108, a brake control module 109 and a steering control module 110 of the communication system 101.

As shown in FIG. 4, a vehicle 104 (such as a car or small vehicle relative to the truck 100) is equipped with a communication system 103, which includes a DSRC radio 112 and a DSRC antenna 111, with the DSRC radio 112 communicating with an Electronic Control Unit (ECU) 113. A forward facing camera 115 is disposed at the vehicle (such as at and behind and viewing through the windshield of the vehicle) and is also in communication with the ECU 113. The ECU 113 is in communication (such as wired or wireless communication) with a vehicle bus of the vehicle 104, and communicates with a Human Machine Interface (HMI) 114 a, a brake control module 114 b and a steering control module 114 c of the communication system 103. The determination of a potential collision may be based at least in part on the communicated data, the predicted paths of travel of the vehicle and truck, and processing of image data captured by the forward viewing camera (such as for situations of the types shown in FIGS. 5 and 6).

In one embodiment (such as shown in FIG. 3), the truck ECU 107 receives vehicle data from the other vehicle 104 via a DSRC link (between the radio 112 and antenna 111 and the radio 106 and antenna 105) and predicts the vehicle path and estimates the truck's path prediction utilizing the truck's vehicle data. A collision estimator of the truck utilizes the predicted path of the truck and the predicted path of the vehicle and estimates the collision probability. If the collision probability exceeds a threshold level, the system alerts the driver of the truck (utilizing the HMI interface 108) of the potential collision. Optionally, if the probability of collision exceeds a second threshold level (which is representative of a greater probability of imminent collision), the system 101 may activate the brakes of the truck and/or may control the steering of the truck to avoid or prevent collision with the nearby vehicle. Optionally, the determination of the probability of collision may be based at least in part on processing of image data captured by a camera of the truck, such as a forward viewing camera (such as disposed at and viewing through a windshield of the cab of the truck for viewing forward so as to capture image data of a vehicle or scene ahead of the truck, such as for situations of the type shown in FIG. 6) or a sideward viewing camera (such as disposed at a side of the cab or trailer of the truck and viewing sideward and/or rearward and/or forward so as to encompass a location where a vehicle may be present as the truck turns in front of the vehicle, such as for situations of the type shown in FIG. 5).

Thus, and such as shown in FIG. 7, the truck system may receive the vehicle data via the DSRC radio at 116 and may select the target object at 117. The truck data is received from the vehicle bus at 118 and the system determines or predicts a path of travel of the truck at 120. The system determines or estimates the probability of collision at 119, and determines if an alert is sufficient or if braking or steering is needed to assist in avoiding collision with the vehicle. The system may then generate an output to the HMI module 108 and/or the brake module 109 and/or the steering system 110 to alert the truck driver and/or control or maneuver the truck to avoid collision with the vehicle.

Optionally, and such as shown in FIG. 4, a vehicle ECU 113 of the car or vehicle 104 receives the truck data from the truck via a DSRC link (between the radio 106 and antenna 105 and the radio 112 and antenna 111) and predicts the truck's path and estimates the vehicle's path prediction utilizing the vehicle's vehicle data. A collision estimator of the vehicle utilizes the predicted path of the truck and the predicted path of the vehicle and estimates the collision probability. If the collision probability exceeds a threshold level, the system alerts the driver of the vehicle (utilizing the HMI interface 114 a) of the potential collision. Optionally, if the probability of collision exceeds a second threshold level (which is representative of a greater probability of imminent collision), the system 103 may activate the brakes of the vehicle and/or may control the steering of the vehicle to avoid or prevent collision with the nearby truck.

Thus, and such as shown in FIG. 8, the vehicle system may receive the truck data via the DSRC radio at 121 and may determine or predict the truck path of travel at 120. The vehicle data is received at 122 and the system determines or predicts a path of travel of the vehicle at 123. The system determines or estimates the probability of collision at 124, and determines if an alert is sufficient or if braking or steering is needed to assist in avoiding collision with the truck. The system may then generate an output to the HMI module 114 a and/or the brake module 114 b and/or the steering system 114 c to alert the vehicle driver and/or control or maneuver the vehicle to avoid collision with the truck.

Therefore, the present invention comprises a vehicle system that utilizes a DSRC communication to transmit or communicate vehicle or truck information or data (indicative of a predicted or projected path of travel of the vehicle or truck) to a system or processor of another vehicle, where the system or processor of the other vehicle may, based on its own projected path of travel, determine if there may be a collision with the vehicle or truck. Thus, if a truck-based system receives a short range communication from a nearby vehicle system and, responsive to processing of vehicle data received from the vehicle system and responsive to truck data indicative of the projected path of the truck, the system may determine if the truck (such as if turning in a direction towards the side of the truck at which the vehicle is located) may collide with the vehicle during the turning maneuver. If such a potential collision is determined likely to occur, the system may alert the driver of the truck and/or may maneuver or control the truck (such as by controlling the steering of the truck and/or the brake system of the truck) to avoid collision with the vehicle.

Optionally, if a vehicle-based system receives a short range communication from a nearby truck system and, responsive to processing of truck data received from the truck system and responsive to vehicle data indicative of the projected path of the vehicle, the system may determine if the truck (such as if the truck is turning in a direction towards the side of the truck at which the vehicle is located) may collide with the vehicle during the turning maneuver. If such a potential collision is determined likely to occur, the system may alert the driver of the vehicle and/or may maneuver or control the vehicle (such as by controlling the steering of the vehicle and/or the brake system of the vehicle) to avoid collision with the turning truck.

Optionally, the communication between the car and truck may comprise other communication means or protocols, such as via car2car or vehicle to vehicle (V2V) and vehicle-to-infrastructure (car2X or V2X or V2I or 4G or 5G a broadband cellular network) technology or the like. Optionally, the system may also communicate with other systems, such as via a vehicle-to-vehicle communication system or a vehicle-to-infrastructure communication system or the like. Such car2car or vehicle to vehicle (V2V) and vehicle-to-infrastructure (car2X or V2X or V2I or 4G or 5G a broadband cellular network) technology provides for communication between vehicles and/or infrastructure based on information provided by one or more vehicles and/or information provided by a remote server or the like.
